Austin Pickett fae9e5677a fix(update): stop reading gateway identity off the Windows restart watcher's argv (#107002) (#121635)
* fix(update): stop reading gateway identity off the restart watcher's argv (#107002)

The detached restart watcher is spawned as
`python -c <watcher source> <old_pid> <python> -m hermes_cli.main gateway run`.
Its trailing argv is the command it will spawn LATER, but the canonical matchers
read identity straight off the joined command line, so the watcher itself was
classified as a live `gateway run` process — the documented "never infer process
identity from argv substrings" bug class, on the exact surface `hermes update`
uses to verify a post-update relaunch.

Also budget the post-relaunch liveness poll against the watcher's own deadline:
the watcher respawns the gateway only after the PID it was handed exits, so a
30 s window can expire before the relaunch it verifies was scheduled to start.

* test(windows-live): run the gateway-ancestor harness parent from a script file

A `python -c <src>` parent is an interpreter running inline source and carries
no readable Hermes identity, so it is no longer a gateway to any classifier —
the harness's own comment already said a realistic gateway argv is not a -c blob.

* test(windows-live): share one sleeper SCRIPT across the live process-topology fixtures

Four live Windows E2E files stood processes up as `python -c "sleep" <hermes argv tail>`.
That shape no longer carries a readable Hermes identity, so the fixtures stopped standing
in for the gateways they simulate. One shared sleeper script replaces the -c spelling.

* fix(gateway): drop the duplicated _INLINE_SOURCE_FLAG_RE definition

The constant was emitted twice around command_line_runs_inline_source. Same
pattern both times, so behaviour is unchanged — but one definition is enough.

* test(stderr-timestamp): run the gateway-lookalike children from script files

Both lookalikes stood a gateway child up as `python -c <src> <gateway tail>`.
That shape no longer carries a readable Hermes identity (#107002), so the
wrapper correctly stopped treating them as gateway spawns and the tests failed.
A `-c` tail is data for a program the inline source may spawn LATER, never the
child's own identity — the real wrapper child is `python -m hermes_cli.main
gateway run`, which has no `-c`. Running the stand-ins from a real script file
restores what the tests mean to assert without depending on the misread.

* test(windows-live): restore the tempfile import dropped with the local sleeper helper

* test(windows-live): wait on the sleeper SCRIPT name, not its source text

The live fixtures proved argv visibility by waiting for `time.sleep(120)` in the
spawned process's command line. That string only ever appeared there because the
sleeper was spelled `python -c "import time; time.sleep(120)"`; now that it runs
from a file the source is in the file, so the probe timed out ("sleeper argv
never visible") even though the argv was perfectly visible.

Wait on the script name instead, exported as SLEEPER_MARKER next to the script
so the probe and the spelling cannot drift apart again.

* fix(tests,gateway): keep the live-system guard blocking -c-wrapped gateway spawns

The #107002 identity fix made _gateway_command_subcommand return None for
'python -c <src> … -m hermes_cli.main gateway run'. tests/_fixtures/live_system_guard.py
shares that matcher, so the autouse guard stopped blocking the detached restart
watcher: real gateways leaked out of the e2e run and squatted the webhook port.

Add gateway.status.gateway_spawn_intent_subcommand — the spawn-intent mirror of the
identity matcher, peeling the inline-source wrapper token-wise and re-running the same
canonical matcher on each suffix (still no substring matching) — and point the guard at
it. Read-only subcommands stay spawnable.

* fix(gateway): make the inline-source option walk value-aware so -X utf8 -c is not read as a gateway

The walk that decides whether a command line is an interpreter running inline
source (`python -c <src> ...`) treated every token starting with `-` as a flag
and the first non-flag token as the end of the option block. CPython options
that take a SEPARATE operand (-X/-W/-Q, --check-hash-based-pycs, --jit) break
that model: the operand was mistaken for the end of the block, so the walk
never reached the -c behind it and the watcher was read as a live gateway
again -- exactly the #107002 misclassification, one shape further out.

- Reuse the canonical operand sets from hermes_state_holders rather than
  hand-rolling a second copy (AGENTS.md: parser-derived flag sets).
- Walk case-preserving tokens: operand-taking -Q/-W/-X must not be conflated
  with operand-less -q/-b, so callers no longer lowercase before the walk.
- Handle clustered short options precisely (-uc is inline source, -Xc is -X c).
- Replace the ad-hoc _INLINE_SOURCE_FLAG_RE rescan in
  gateway_spawn_intent_subcommand with the index the same walk returns; the
  regex could not find spellings the walk accepts and would raise
  StopIteration.

Hermes Agent

Hermes Agent ☤

Hermes Agent | Hermes Desktop

Documentation Discord License: MIT Built by Nous Research 中文 اردو Español

The self-improving AI agent built by Nous Research. It's the only agent with a built-in learning loop — it creates skills from experience, improves them during use, nudges itself to persist knowledge, searches its own past conversations, and builds a deepening model of who you are across sessions. Run it on a $5 VPS, a GPU cluster, or serverless infrastructure that costs nearly nothing when idle. It's not tied to your laptop — talk to it from Telegram while it works on a cloud VM.

Use any model you want — Nous Portal, OpenRouter, OpenAI, your own endpoint, and many others. Switch with hermes model — no code changes, no lock-in.

A real terminal interfaceFull TUI with multiline editing, slash-command autocomplete, conversation history, interrupt-and-redirect, and streaming tool output.
Lives where you doTelegram, Discord, Slack, WhatsApp, Signal, and CLI — all from a single gateway process. Voice memo transcription, cross-platform conversation continuity.
A closed learning loopAgent-curated memory with periodic nudges. Autonomous skill creation after complex tasks. Skills self-improve during use. FTS5 session search with LLM summarization for cross-session recall. Honcho dialectic user modeling. Compatible with the agentskills.io open standard.
Scheduled automationsBuilt-in cron scheduler with delivery to any platform. Daily reports, nightly backups, weekly audits — all in natural language, running unattended.
Delegates and parallelizesSpawn isolated subagents for parallel workstreams. Write Python scripts that call tools via RPC, collapsing multi-step pipelines into zero-context-cost turns.
Runs anywhere, not just your laptopSeven terminal backends — local, Docker, SSH, Singularity, Modal, Daytona, and Vercel Sandbox. Daytona and Modal offer serverless persistence — your agent's environment hibernates when idle and wakes on demand, costing nearly nothing between sessions. Run it on a $5 VPS or a GPU cluster.
Research-readyBatch trajectory generation, trajectory compression for training the next generation of tool-calling models.

Quick Install

Linux, macOS, WSL2

curl -fsSL https://hermes-agent.nousresearch.com/install.sh | bash

Windows (native, PowerShell)

Heads up: Native Windows runs Hermes without WSL — CLI, gateway, TUI, and tools all work natively. If you'd rather use WSL2, the Linux/macOS one-liner above works there too. Found a bug? Please file issues.

Run this in PowerShell:

iex (irm https://hermes-agent.nousresearch.com/install.ps1)

The source installer delegates Python 3.14, Node.js, npm, ripgrep, FFmpeg, and Python dependencies to PM. If Git is absent, it stages the verified Git for Windows archive in Hermes' tool store. It does not replace your system Git. See installation methods for the separate MSIX/App Installer package and its update ownership.

Android / Termux: A signed APT repository is available for aarch64 devices, with a stable channel (tagged releases) and a prerelease canary channel. The package includes Python, Node.js, and the TUI. Use the Termux guide, not the desktop/server installer script.

Windows: Native Windows is fully supported — the PowerShell one-liner above installs everything. If you'd rather use WSL2, the Linux command works there too. Native Windows install lives under %LOCALAPPDATA%\hermes; WSL2 installs under ~/.hermes as on Linux.

After installation:

source ~/.bashrc    # reload shell (or: source ~/.zshrc)
hermes              # start chatting!

Troubleshooting

Windows Defender or antivirus flags uv.exe as malware

If your antivirus (Bitdefender, Windows Defender, etc.) quarantines uv.exe from the Hermes bin folder (%LOCALAPPDATA%\hermes\bin\uv.exe), this is a false positive. The file is Astral's uv — the Rust Python package manager Hermes bundles to manage its Python environment. ML-based antivirus engines commonly flag unsigned Rust binaries that download and install packages.

To verify your copy is authentic:

# Install GitHub CLI if needed
winget install --id GitHub.cli

# Login to GitHub
gh auth login

# Run verification
$uv = "$env:LOCALAPPDATA\hermes\bin\uv.exe"
$ver = (& $uv --version).Split(' ')[1]
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
$zip = "$env:TEMP\uv.zip"
Invoke-WebRequest "https://github.com/astral-sh/uv/releases/download/$ver/uv-x86_64-pc-windows-msvc.zip" -OutFile $zip -UseBasicParsing
gh attestation verify $zip --repo astral-sh/uv
Expand-Archive $zip "$env:TEMP\uv_x" -Force
(Get-FileHash "$env:TEMP\uv_x\uv.exe").Hash -eq (Get-FileHash $uv).Hash

If attestation says "Verification succeeded" and the last line prints True, you're good.

To whitelist Hermes:

  • Windows Defender: Run PowerShell as Admin → Add-MpPreference -ExclusionPath "$env:LOCALAPPDATA\hermes\bin"
  • Bitdefender: Add an exception in the Bitdefender console (Protection > Antivirus > Settings > Manage Exceptions)
  • Whitelist the folder, not the file hash — Hermes updates uv and the hash changes every version

For more context, see the upstream Astral reports: astral-sh/uv#13553, astral-sh/uv#15011, astral-sh/uv#10079.

Skip the API-key collection — Nous Portal

Hermes works with whatever provider you want — that's not changing. But if you'd rather not collect five separate API keys for the model, web search, image generation, TTS, and a cloud browser, Nous Portal covers all of them under one subscription:

  • 300+ models — pick any of them with /model <name>
  • Tool Gateway — web search, image generation (FAL), text-to-speech (OpenAI), cloud browser (Browser Use), all routed through your sub. No extra accounts.

One command from a fresh install:

hermes setup --portal

That logs you in via OAuth, sets Nous as your provider, and turns on the Tool Gateway. Check what's wired up any time with hermes portal info. Full details on the Tool Gateway docs page.

You can still bring your own keys per-tool whenever you want — the gateway is per-backend, not all-or-nothing.


CLI vs Messaging Quick Reference

Hermes has two entry points: start the terminal UI with hermes, or run the gateway and talk to it from Telegram, Discord, Slack, WhatsApp, Signal, or Email. Once you're in a conversation, many slash commands are shared across both interfaces.

Action CLI Messaging platforms
Start chatting hermes Run hermes gateway setup + hermes gateway start, then send the bot a message
Start fresh conversation /new or /reset /new or /reset
Change model /model [provider:model] /model [provider:model]
Set a personality /personality [name] /personality [name]
Retry or undo the last turn /retry, /undo /retry, /undo
Compress context / check usage /compress, /usage, /insights [--days N] /compress, /usage, /insights [days]
Browse skills /skills or /<skill-name> /<skill-name>
Interrupt current work Ctrl+C or send a new message /stop or send a new message

Migrating from OpenClaw

If you're coming from OpenClaw, Hermes can automatically import your settings, memories, skills, and API keys.

During first-time setup: The setup wizard (hermes setup) automatically detects ~/.openclaw and offers to migrate before configuration begins.

Anytime after install:

hermes claw migrate              # Interactive migration (full preset)
hermes claw migrate --dry-run    # Preview what would be migrated
hermes claw migrate --preset user-data   # Migrate without secrets
hermes claw migrate --overwrite  # Overwrite existing conflicts

What gets imported:

  • SOUL.md — persona file
  • Memories — MEMORY.md and USER.md entries
  • Skills — user-created skills → ~/.hermes/skills/openclaw-imports/
  • Command allowlist — approval patterns
  • Messaging settings — platform configs, allowed users, working directory
  • API keys — allowlisted secrets (Telegram, OpenRouter, OpenAI, Anthropic, ElevenLabs)
  • TTS assets — workspace audio files
  • Workspace instructions — AGENTS.md (with --workspace-target)

See hermes claw migrate --help for all options, or use the openclaw-migration skill for an interactive agent-guided migration with dry-run previews.
